Using Registry module crashes Perl with Access Violation

Our perl program crashes when started on customer's Windows machine. Further tests shows that with the perl distribution we provide, a simple "hello world" script works, but breaks if it includes the line:

use Win32::TieRegistry(Delimiter=>'\\');

It crashes with Access Violation for accessing a zero pointer. The stack points to registry.dll.

Any idea how I can troubleshoot this problem? I didn't find anything about it in a google search, and can't recreate it in my environment.

Can you tell me what version of perl you are using? Is it Activestate or Strawberry Perl?

An access violation is usually a programming error in some non perl code. It looks like could be registry.dll that contains the error. In order to track it down you would probably need source code and/or debugger. I am assuming that the registry.dll is a dll that comes as part of perl (ie XS/C code part of Win32::TieRegistry or Win32API::Registry that is used by Win32::TieRegistry). To validate this assumption can you provide the full path to registry.dll? I think it will show it in the Access Violation dialog box.
